Existing technologies mainly include endoscopic clip closure technology and nylon rope / suture combined endoscopic clip purse-string suturing technology. These technologies are reliable and have low medical costs, and are popular and widely used. The existing endoscopic clip structure used under soft endoscopy includes a clamping and locking structure, which allows the endoscopic clip to have a certain length of space to arrange the two parts of the structure. The above structural features make the endoscopic clip structure more complex and require a larger operating space; in particular, for the purse-string suturing technology, due to the certain height of the endoscopic clip, the endoscopic clip is easy to fall over during the purse-string suturing process, which hinders the closure of the endoscopic clip, which greatly affects the operation efficiency and even leads to operation failure.

[0070] For ease of understanding, the following Figures 1 to 22 The illustrated stapler illustrates the specific structure of the simple closure clip release device.

[0071] like Figures 1 to 22 As shown, the simple closing clip releasing device 500 for releasing the closing clip 200 provided in the embodiment of the first aspect of the present application includes: a seat body 10 , a mounting shell 20 , a clamp pushing plate 30 and a control assembly 40 .

[0072] The base body 10 is configured to be connected to the endoscope 100 . Specifically, a mounting hole 11 is provided on the base body 10 . The endoscope 100 is inserted into the mounting hole 11 so that the base body 10 is mounted on the endoscope 100 .

[0073] The mounting shell 20 is arranged on the seat body 10, and the mounting shell 20 has a mounting space and a clamp outlet, a one-way clamping structure 21 is arranged in the mounting space, and the one-way clamping structure 21 is configured to be one-way clamped with the closing clamp 200 so that the closing clamp 200 can move in one direction; specifically, the clamp outlet is connected to the mounting space, and the mounting space has a bottom wall and a side wall arranged along the circumference of the bottom wall, and the one-way clamping structure 21 is arranged on the side wall; the one-way clamping structure 21 is a clamping sheet. In a specific embodiment of the present application, the mounting shell 20 includes: a shell 25 and a cover plate 26. The shell 25 includes a bottom plate and a side plate, the push clamp plate 30 is arranged on the bottom plate, the one-way clamping structure 21 is arranged on the side plate, and the side plate is provided with a first connecting structure 251. The cover plate 26 is covered on the housing 25 and forms an installation space with the housing 25. The cover plate 26 is provided with a second connection structure 261 that matches the first connection structure 251. One of the first connection structure 251 and the second connection structure 261 is a connection groove, and the other is a guide rail. Specifically, the first connection structure 251 can be a connection groove or a guide rail, and correspondingly, the second connection structure 261 can be a connection groove or a guide rail. Those skilled in the art can select the setting of the connection groove and the guide rail according to their needs.

[0074] The push clamp plate 30 is located in the installation space and is arranged on the bottom wall of the installation shell 20. The push clamp plate 30 can move in the direction close to or away from the clamp outlet. At least one installation position 31 is provided on the push clamp plate 30, and the installation position 31 is configured to fix the closing clip 200. In a specific embodiment of the present application, there is an elastic limiting structure on the installation position 31, and the elastic limiting structure is configured to cooperate with the closing clip 200 so that the push clamp plate 30 can drive the closing clip 200 to move. The elastic limiting structure includes a plurality of spring pieces 311, and the closing clip 200 is fixed to the push clamp plate 30 through the plurality of spring pieces 311.

[0075] The control assembly 40 is connected to the pushing clamp plate 30 , and the control assembly 40 is configured to control the pushing clamp plate 30 to move relative to the mounting shell 20 .

[0076] The simple closing clip releasing device 500 provided in the present application has a push plate 30 that fixes the closing clip 200 through the mounting position 31, and controls the movement of the push plate 30 relative to the mounting shell 20 through the control component 40, so that the closing clip 200 set on the push plate 30 is pushed out from the clamp outlet to suture the human tissue wound 400. During the movement of the push plate 30, due to the limitation of the one-way clamping structure 21, the closing clip 200 on the push plate 30 can only move toward the clamp outlet. During the above-mentioned suturing process, multiple closing clips 200 can be installed and released one by one, thereby improving the operating efficiency.

[0077] In addition, the simple closing clip release device 500 has fewer components, a simple structure, and no complicated connection relationship between the components. On the one hand, the product layout is more concise, occupies less space, is easy to install and maintain, and makes the product suitable for more scenarios, especially for narrow operating spaces. On the other hand, the complexity and failure rate of the product are reduced, and the reliability and stability of the system are improved.

[0078] like Figures 1 to 22 As shown, the specific operation process of the simple closing clip release device 500 is as follows:

[0079] In the first step, the closing clip 200 is installed on the installation position 31 of the pushing clamp plate 30, and then the seat body 10 is connected to the front end of the endoscope 100, and then the simple closing clip release device 500 is introduced into the surgical operation site in the human body together with the endoscope 100.

[0080] The second step is to clamp or anchor the human tissue to be sutured by using an existing endoscopic instrument such as endoscopic forceps, and then pull the human tissue to the clamp outlet.

[0081] In the third step, the control component 40 controls the pushing clamp plate 30 to move toward the clamp outlet until part of the closing clamp 200 passes through the clamp outlet, and then changes the closing clamp 200 from an open state to a sutured state to suture the human tissue wound 400 (after the closing clamp 200 is separated from the pushing clamp plate 30, the closing clamp 200 changes from an open state to a sutured state under the action of its own elastic force; or, under the action of the two clamping arms, the closing clamp 200 is squeezed and deformed, and changes from an open state to a sutured state).

[0082] In the fourth step, the control component 40 is used to control the pushing plate 30 to move away from the clamp outlet. During this process, due to the action of the one-way clamping structure 21, the closing clip 200 is disengaged from the mounting shell 20. At the same time, the next closing clip 200 moves forward relatively on the pushing plate 30, so that the next closing clip 200 enters the frontmost mounting position 31 of the pushing plate 30, preparing for the second suturing.

[0083] like Figures 1 to 7 , Figures 9 to 12 As shown, in one embodiment of the present application, a first limiting structure 22 is provided on the bottom wall, and a second limiting structure 32 matching with the first limiting structure 22 is provided on the push clamp plate 30 .

[0084] One of the first limiting structure 22 and the second limiting structure 32 is a limiting groove, and the other is a sliding member. The limiting groove extends along the moving direction of the push clamp 30, and the sliding member can slide in the limiting groove. Specifically, the first limiting structure 22 can be a limiting groove or a sliding member, and correspondingly, the second limiting structure 22 can be a sliding member or a limiting groove. Those skilled in the art can select the setting of the limiting groove and the sliding member according to their needs.

[0085] The cooperation between the sliding member and the limiting groove limits the moving distance of the pushing clamp plate 30, so that the moving distance of the pushing clamp plate 30 is just enough to push a closing clamp out of the clamp outlet, thereby avoiding the situation where the pushing clamp plate 30 moves too far and the closing clamp 200 cannot effectively suture the human tissue wound 400, thereby reducing the probability of misoperation and ensuring the product stability and reliability.

[0086] like Figures 1 to 7 , Figures 9 to 12 As shown, in one embodiment of the present application, a suture groove 23 is provided on the mounting shell 20 , the suture groove 23 is communicated with the clamp outlet, and the suture groove 23 is configured to accommodate a human tissue wound 400 .

[0087] The pushing clamp plate 30 is provided with an escape space 33 which matches the shape of the suture groove 23 .

[0088] The suturing groove 23 provides a suturing space for human tissue. During the suturing process, the human tissue only needs to be pulled into the suturing space, and the closing clamp 200 can suturing the human tissue in the suturing groove 23. The operator does not need to ensure that the closing clamp 200 is aligned with the human tissue to be sutured in real time, thereby reducing the suturing difficulty and ensuring the suturing efficiency. At the same time, the suturing accuracy of the closing clamp 200 on the human tissue can also be ensured.

[0089] Several embodiments of the control component 40 are described in detail below with reference to the accompanying drawings.

[0090] Embodiment 1

[0091] like Figures 1 to 7 , Figures 9 to 12 As shown, the control assembly 40 includes: a first control rope 41 , a fixed pulley 42 and a second control rope 43 .

[0092] The first control cable 41 is connected to the clamping plate 30 , and the first control cable 41 is configured to control the clamping plate 30 to move in a direction away from the clamping outlet.

[0093] The fixed pulley 42 is disposed on the bottom wall or the seat body 10 and can rotate relative to the bottom wall or the seat body 10 .

[0094] After the second control cable 43 passes around the fixed pulley 42, it is connected to the pushing clamp plate 30. The second control cable 43 is configured to control the pushing clamp plate 30 to move toward the direction close to the clamp outlet. When the fixed pulley 42 is arranged on the seat body 10, the seat body 10 is provided with a mounting groove 12 and a wire groove 13. The fixed pulley 42 is at least partially arranged in the mounting groove 12, the second control cable 43 is located in the wire groove 13, and part of the fixed pulley 42 passes through the bottom wall to ensure that the second control cable 43 is connected to the pushing clamp plate 30.

[0095] The operation process of the above control component 40 is as follows:

[0096] The second control rope 43 is dragged, and the second control rope 43 drives the pushing clamp plate 30 to move toward the clamp outlet until part of the closing clamp 200 passes through the clamp outlet, and then the closing clamp 200 is changed from the open state to the suture state to suture the human tissue wound 400 (after the closing clamp 200 is separated from the pushing clamp plate 30, the closing clamp 200 is changed from the open state to the suture state under the action of its own elastic force; or, under the action of the two clamping arms, the closing clamp 200 is squeezed and deformed, and changed from the open state to the suture state); after the suturing is completed, the first control rope 41 is dragged, and the first control rope 41 drives the pushing clamp plate 30 away from the clamp outlet, so that the next closing clamp 200 moves on the pushing clamp plate 30 until the next closing clamp 200 enters the frontmost mounting position 31 of the pushing clamp plate 30, preparing for the second suturing.

[0097] The structure of the control assembly 40 can realize the movement of the push plate 30 by dragging the first control cable 41 and the second control cable 43, and the structure is simple. In addition, the forward and backward movement of the push plate 30 is driven by the two control cables, ensuring that there is sufficient driving force to drive the push plate 30.

[0098] Embodiment 2

[0099] like Figures 19 to 22 As shown, in one embodiment of the present application, the control assembly 40 includes a push-pull cable 44 and an elastic member 45, and the elastic member 45 is arranged between the push clamp plate 30 and the support surface 70. The support surface 70 can be arranged on the mounting shell 20, or a structure having a support surface 70 is separately arranged.

[0100] The push-pull cable 44 is configured to control the clamping plate 30 to move toward or away from the clamping outlet.

[0101] The push-pull cable 44 is pushed, and the push-pull cable 44 drives the push clamp plate 30 to move toward the clamp outlet until part of the closing clamp 200 passes through the clamp outlet. During this process, the elastic member 45 releases its elastic force to assist the movement of the push clamp plate 30, and then changes the closing clamp 200 from the open state to the suture state to suture the human tissue wound 400 (after the closing clamp 200 is separated from the push clamp plate 30, the closing clamp 200 changes from the open state to the suture state under the action of its own elastic force; or, under the action of the two clamping arms, the closing clamp 200 is squeezed and deformed, and changes from the open state to the suture state); after the suturing is completed, the push-pull cable 44 is dragged, and the push-pull cable 44 drives the push clamp plate 30 away from the clamp outlet, so that the next closing clamp 200 moves on the push clamp plate 30 until the next closing clamp 200 enters the frontmost mounting position 31 of the push clamp plate 30, preparing for the second suturing. During this process, the elastic member 45 accumulates force.

[0102] The structure of the control assembly 40 can realize the movement of the push clamp 30 by dragging or pushing and pulling the push-pull cable 44. The structure is simple, which reduces the complexity and failure rate of the product, makes the product layout more concise, and improves the reliability and stability of the system.

[0103] Several embodiments of controlling the closure clip 200 to change from the open state to the suturing state are described in detail below with reference to the accompanying drawings.

[0104] Embodiment 1

[0105] like Figures 1 to 7 , Figures 9 to 12As shown, in one embodiment of the present application, a third limiting structure 24 is provided on the bottom wall of the mounting shell 20 and / or the pushing clamp plate 30; the third limiting structure 24 is configured to cooperate with the fourth limiting structure 201 on the closing clamp 200. The third limiting structure 24 includes symmetrically arranged guide grooves or symmetrically arranged slide rails, and the guide grooves or slide rails extend along the moving direction of the pushing clamp plate 30.

[0106] The elastic closing clip 200 is installed on the installation position 31, and the fourth limiting structure is matched with the third limiting structure 24 so that the closing clip 200 is opened and is in an open state; when part of the closing clip 200 is pushed out of the clamp outlet, the pushing clamp plate 30 is controlled to move away from the clamp outlet. The closing clip 200 cannot move with the pushing clamp plate 30 due to the limiting effect of the one-way clamping structure 21, so that the closing clip 200 is gradually separated from the pushing clamp plate 30. When the closing clip 200 is completely separated from the pushing clamp plate 30 (the fourth limiting structure is separated from the third limiting structure 24 at the same time), the closing clip 200 is closed from the open state to the suture state under the action of elasticity, and the closing clip 200 is fixed on the human tissue.

[0107] Embodiment 2

[0108] like Figures 14 to 17 As shown, in one embodiment of the present application, the simple closing clip releasing device 500 further includes: two clamping arms 50 and a push-pull member 60 .

[0109] The two clamping arms 50 are hinged and arranged on the mounting shell 20 . The two clamping arms 50 are configured to control the closing clip 200 to change from an open state to a suturing state.

[0110] The push-pull member 60 is connected to the two clamping arms 50 , and the push-pull member 60 is configured to control the relative rotation of the two clamping arms 50 .

[0111] Specifically, the clamping arm 50 includes a connecting end and a clamping end that are arranged opposite to each other, the clamping end cooperates with the closing clamp 200 , and the connecting end is connected to the push-pull member 60 .

[0112] After the partially closed clamp 200 is pushed out of the clamping opening, the partially closed clamp 200 is located between the clamping ends of the two clamping arms 50, and then the push-pull member 60 is dragged, and the push-pull member 60 drives the clamping arms 50 to rotate relative to the mounting shell 20, so that the clamping ends of the two clamping arms 50 are closed, and the two clamping arms 50 deform the closed clamp 200, so that the closed clamp 200 changes from an open state to a sutured state, and the human tissue is sutured.

[0113] The structure for controlling the state change of the closing clip 200 can change the closing clip 200 from an open state to a sutured state by closing the two clamping arms 50 through the push-pull member 60. The structure is simple, reduces the complexity of the product, and does not require special elastic materials to make the closing clip 200, thereby reducing the manufacturing difficulty and production cost of the product.

[0114] In one embodiment of the present application, a clamping groove 51 is provided on the clamping arm 50 , and two clamping grooves 51 constitute a clamping space, which is connected to the installation space through a clamp outlet, and the clamping space is configured to accommodate the closing clip 200 .

[0115] Since the closing clip 200 needs to be deformed by squeezing the clamping arms 50 to sew the human tissue, after the clamping ends of the two clamping arms 50 are closed, the suturing groove 23 between the two clamping arms 50 forms an accommodating space for the deformed closing clip 200, thereby ensuring the shape of the deformed closing clip 200 and avoiding the problem of poor suturing effect caused by excessive deformation of the closing clip 200, that is, ensuring the reliability of the closing clip 200.

[0116] In one embodiment of the present application, an anti-dropout limiting structure is provided on the groove wall of the clamping groove 51 , and the anti-dropout limiting structure is configured to cooperate with the closing clip 200 .

[0117] The setting of the anti-slip limit structure, on the one hand, prevents the closing clip 200 from slipping out of the clamping groove 51, and avoids the situation where the closing clip 200 slips out and the closing clip 200 needs to be reinstalled due to insufficient quantity, thereby ensuring the suturing effect and suturing efficiency of the product. On the other hand, it plays a limiting role on the closing clip 200, avoiding the movement or shaking of the closing clip 200 during the deformation process, that is, ensuring the deformation reliability of the closing clip 200.

[0118] Embodiment 3

[0119] In one embodiment of the present application, a third limiting structure 24 is provided on the bottom wall of the mounting shell 20 and / or the clamping plate 30; the third limiting structure 24 is configured to cooperate with a fourth limiting structure 201 on the closing clip 200. The third limiting structure 24 is two side surfaces provided on the clamping plate 30 along its moving direction.

[0120] The elastic closing clip 200 is installed on the installation position 31, and the fourth limiting structure is clamped on the side of the pushing clamp plate 30, so that the closing clip 200 is opened and is in an open state; when part of the closing clip 200 is pushed out of the clamp outlet, the pushing clamp plate 30 is controlled to move away from the clamp outlet, and the closing clip 200 cannot move with the pushing clamp plate 30 due to the limiting effect of the one-way clamping structure 21, so that the closing clip 200 is gradually separated from the pushing clamp plate 30. When the closing clip 200 is completely separated from the pushing clamp plate 30 (the fourth limiting structure is separated from the third limiting structure 24 at the same time), the closing clip 200 is closed from the open state to the suture state under the action of elasticity, and the closing clip 200 is fixed on the human tissue.

[0121] Those skilled in the art should understand that the solutions in Example 1 and Example 3 may exist at the same time, specifically: a third limiting structure may be provided on the bottom wall of the mounting shell 20, and at the same time, the two side surfaces of the push clamp plate 30 arranged along its moving direction may also act as the third limiting structure, so that the closing clamp 200 is in an open state. The above-mentioned arrangement enables the push clamp plate 30 to move smoothly with less resistance.

[0122] like Figures 1 to 22 As shown, the suturing device provided by the embodiment of the second aspect of the present application includes: the above-mentioned simple closure clip releasing device 500 and the closure clip 200.

[0123] The closing clip 200 is arranged on the installation position 31 of the pushing clip plate 30 of the simple closing clip releasing device 500 , and the closing clip 200 is provided with a matching structure adapted to the one-way clamping structure 21 of the installation space of the simple closing clip releasing device 500 .

[0124] The present application provides a suturing device that can be installed with multiple closing clips 200 to achieve release of multiple clips one by one, thereby improving operating efficiency; suturing is achieved through its own elasticity or extrusion puncture deformation, with a simple structure and small size. During the purse-string suturing process, there is no situation where the closing clip falls over and hinders the suturing, thereby improving the success rate and efficiency of the suturing.

[0125] like Figure 4b and Figure 5 As shown, in one embodiment of the present application, a fourth limiting structure 201 is provided on the closing clip 200, and the fourth limiting structure includes two symmetrically arranged protrusions.

[0126] The two protrusions are respectively pressed against two sides of the pushing clamping plate 30 or inserted into the guide grooves on the bottom wall of the mounting shell 20 or the guide grooves of the pushing clamping plate 30 .

[0127] In one embodiment of the present application, a fourth limiting structure 201 is provided on the closing clip 200 , and the fourth limiting structure includes two symmetrically arranged limiting grooves.

[0128] The two limiting grooves are respectively matched with the slide rails on the bottom wall of the mounting shell 20 or the slide rails on the push clamping plate 30 .

[0129] The fourth limiting structure is simple in structure and enables the closing member to be in an open state, which facilitates the installation and release of the closing clip.

[0130] like Figures 1 to 22 As shown, in one embodiment of the present application, two puncture portions 202 are symmetrically arranged on the closing clip 200, and the two puncture portions 202 extend toward each other.

[0131] The puncture portion 202 can be inserted into human tissue, so that the closing clip 200 is more firmly fixed on the human tissue, thereby improving the reliability of suturing of the closing clip 200.

[0132] like Fig.18 As shown, in one embodiment of the present application, a barb stopper 204 is provided on the closing clip 200 .

[0133] When the closing clip 200 is fixed on human tissue, the barb limiting portion 204 and the puncture portion 202 penetrate into the human tissue at the same time, and the barb limiting portion 204 can further stably fix the closing clip 200 on the human tissue, thereby reducing the probability of the closing clip 200 slipping off, and can more effectively suture the human tissue, which is particularly suitable for suturing some parts with greater mobility or wounds that need to withstand greater tension.

[0134] like Figures 9 to 13 As shown, in one embodiment of the present application, the stapler further includes a suture 300 , and the suture 300 is connected to the closing clip 200 .

[0135] When the wound 400 on the human tissue is relatively large, multiple closing clips 200 are fixed to the human tissue along the circumference of the wound 400, and then the suture 300 is pulled, and the suture 300 brings the multiple closing clips 200 together. As the multiple closing clips 200 gradually gather together, the wound 400 is sutured.

[0136] like Figures 9 to 13 As shown, in one embodiment of the present application, the closing clip 200 is provided with a thread hole 203 for the suture 300 to pass through.

[0137] The provision of the thread hole 203 facilitates the connection between the suture 300 and the closing clip 200. In addition, the thread hole 203 enables the suture 300 to be located at a specific position of the closing clip 200, so that during the process of dragging the suture 300, the suture 300 can drive multiple closing clips 200 to gather together effectively, thereby improving the quality of suturing.
